AT&T taps YouTube 'talent' for Snapchat 'shows'

Oh, by the way: July 15, 2009

Here's some of the other stuff that happened in the wide world of mobile for Wednesday, July 15th, 2009:

Pantech's SKY division has announced the IM-S480S "Tilt" flip for the South Korean market to be offered through carrier SK Telecom. It's a fairly ordinary phone -- 2 megapixel camera, microSD expansion -- but it apparently gets its name from its curved halves (how that evokes a name like "Tilt," we're not exactly sure) and features a trick LED bar above the keypad that can be used to indicate download progress and the like.

Samsung has rolled out a so-called Elegant Edition of its S7350 slider in Hong Kong. It's pink and comes with a quilted pink leather pouch, so... you know, you'd better really be into pink. It also features customized "smart seasonal wallpaper" that'll change based on seasons and calendar events. [Via Unwired View]

It looks like BlackBerry OS 5.0 will get tabbed browsing, a feature that's become virtually standard across smartphone platforms (and has even started to invade the upper dumbphone echelon recently).
